in starting with UB1 (uncommitted bit), followed by the
remaining control bits and the data byte. The least sig-
nificant bit (LSB) of the data byte (D0) is the last bit
clocked into the shift register (Figure 2).
Table 3 is an example of a 16-bit input word. It per-
forms the following functions:
80 hex (128 decimal) loaded into DAC registers
A and B.
DAC A and DAC B are active.
Table 4 shows code examples and how to calculate
their corresponding outputs.
